Why Rent a Generator?

Renting a power generator from H.O. Penn is smart choice for many businesses. Some of the reasons our clients in New York rent a power generator, heater or a/c unit from us include the following:

  • Temporary expansion: If you’re a manufacturer expanding production to meet a one-off order or if you’ve been displaced from your facility for repairs or renovations, renting a generator set is a cost-effective way to power a temporary workspace. Likewise, you can also add an a/c or heater unit to keep your staff comfortable while they work.
  • Remote work: Construction companies, film crews and other operations working far from a normal power source often rely on our rental generator sets. We offer models that are easily portable for deployment in hard-to-get-to spots.
  • Lighting: Keep your crew working around the clock with a generator and lighting rig from H.O. Penn. Our rental products are also useful for special events and other outdoor activities.
  • Disaster recovery: When Hurricane Sandy hit the East Coast in October 2012, H.O. Penn generators were essential in powering the area’s recovery. Our entire fleet of rental generators was busy 24/7 supplying over 100MW of power to rescue crews.
